Yeah, after a little more research I think I'll save up for kevlar tires and carry a spare tube. Years ago I "managed" a bike shop (sat at the register :-) But I got the owner to teach me basic bike ops. No matter though, I never want to fix a flat on the road. Ironically I have never gotten one from the huffy I had as a kid to my Gary Fisher rides in the woods in the 80s to my road rides with my son. Now I've probably cursed myself.
